| titleOfInvention | Preparation process of selenium-rich spring water |
| abstract | The invention discloses a preparation process of selenium-rich spring water, which comprises the following steps: (1) carrying out precipitation treatment; (2) removing microorganisms; (3) selenium enrichment treatment: adding modified chitosan into the mountain spring water after microorganisms are removed to adsorb selenium ions, stirring for 30-40min at the speed of 50-100r/min, taking out the modified chitosan after selenium ions are adsorbed, then treating the mountain spring water for 10-20min by using electromagnetic pulse with single pulse energy of 20-100J and frequency of 65-120KHz, adding the modified chitosan after selenium ions are adsorbed again, treating the mountain spring water for 120-fold and 150min by using ultrasonic with the power of 1500-fold and 2000W, and filtering by using an ultrafiltration membrane to obtain filtrate which is the selenium-rich mountain spring water. The preparation process is simple and feasible, the process is controllable, and the prepared selenium-rich spring water has high selenium content, good quality and wide market popularization value. |
